Does "Fast" = "Detailed"?

I Like MdHoover's description. He took the words right out of my head. As close to reality to me is plenty fast and detailed. Close to real would also encompass warm and detailed as well. Those Mac amps can be pretty warm and detailed, Grant.

Every "fast" system that I have heard (as described by others) has been detailed, clear and without bloom. None have been what I'd consider warm and inviting. One or two have been cold, clinical and I could not listen for more than about an hour before getting a headache. Maybe I haven't yet heard the right "fast" system.

BTW, my VAC, Von Schweikert VR4 Gen III, APL Denon 3910 system is one I consider fast, although it has some bloat in the bass, so it is not as fast as others I have heard. It certainly makes the music sound real, though. Interestingly, the tube amp produces more realistic bass than any SS amp I have owned because all the solid state amps tend to overload the room with bass so the tonal balance can seem out of whack.

I regard my system as fast and detailed. I have no interest in a system that sounds as you describe. A good ribbon or electrotstatic system combined with tubes is fast and not at all cold or clynical. e.g.My Moscode and M/L CLS or Soundlabs with an Atma-Sphere amp.

fast = -LOG (square root of detail/ x-1)

If Bob has an amp playing Chicago at 100 Vus and Timmy's amp plays Boston at 5 VuS but has been warming up for an hour ....

The term "tight bass" is often used to describe a restriction in the drivers harmonics that increases sensitivity and detail.
